I swear there's only 11 hidden money in the restaurant, but the game says there's 12. I even started a new game and fast-forwarded to the day you start your job.

yeah i found your twelfth: she's blocking the items. Click her so you can see past her, click her to get your 12
another way of finding the twelfth is by waiting INSIDE the restaurant until night then use the hint finder thing, that's how I did it!!!
